Battery

Battery chemistry LFP packs tolerate regular charging to 100%; NMC packs are usually happier kept below it.

LFP

Usable capacity What you can actually take out, which is less than the figure on the box.

2.4 kWh

Continuous output 800 W as it comes. The 2,400 W needs a Part P electrician to hardwire it, and it peaks at 3,600 W for a fifth of a second.

2.4 kW

Round trip efficiency Measured by Notebookcheck, which got almost 90% of what it put in back out again. Zendure publishes only 99.9% MPPT efficiency, which is a different thing: that is how well it tracks the panels, not how much survives a charge and a discharge.

Operating temperature The range the maker will stand behind. The cold end is the one that matters in a British garden, and a battery that stops charging at zero stops charging most winter mornings.

Weather rating The IP rating: the first digit is how well it keeps dust out, the second water. Below IP65 it wants to be indoors. Ranked as the higher number, though strictly a 7 is an immersion test where a 6 is a jets test, so one does not always include the other.
